ROADWAY FOR VEHICLES.

Specification of Letters Patent.

Patented June 11, 1907.

Application tiled August 23,1906. Serial No. 331,816.

Be it known that I, ZACHARY Swuuxrn', of Columbus, in the county oi'v Bartholomew and State of Indiana, have invented certain new and useful Improvements in Roadways `t'or Motor-Vehicles; and .l do hereby declare that the following is a tull, clear, and exact description thereof, reference heilig had to the accompanying drawings, and to the letters ot reference marked thereon, which torni a part ot this specitication.

This invention. relates to improvements in roadways for vehicles and rel'ers more especially to a roadway designed lor use in connection with inotor-prrmelleil vehicles.

Among the objects ot the invention is that to provide a roadway which may be economically constructed and along which inoto'r-propelled vehicles as now constructed inay move and which may be used i'or the purpose of connnon carriers. allowing motorpropelled vehicles to make turns and still reinain upon the track though the wlieels oi" said vehicle inay not move in tle same track.

.ln the drawings Figure l is a sectional view ot' the roadway made in accordance with iny invention. Fig. 2 is a view presented `troni standing upon the track. Fig. 3 is a perspective view of a turn in the roadway. l

The roadway is composed oll concrete ol` soine forni, preferably cement, and is made in one piece, doing away with cross ties, spikes, bolts, etc.

As shown in said drawings, A designates a cross bar ot cement holding tlie two tracks be placed as close bars placed in the material composing the sections while in the process ot being manu- .'iactured to prevent the sections 'lrom bes coming disjointed and disarranged by changes ol" temperature or other causes. lt may also be built ol` reinliorced concrete, or any other material as lthe material oit which it is composed is not essential to my invention.

Fig. 2% rei'iresents a turn in the roadway in which the rail on one side is nia-de ot regular construction and the vopposite rail is delecl'cd Ll'roin its usual course so as to come `nearer to inside rail than when moving upon a straiglet line. 'lhis is vlor the purpose o'l controlling the hind wheels ol' a motor-propelled vehicle which do not track with the lore wheels so as to make the turn and still keep on the track.

ln Fig. I A represents the usual track; the inside dotted line, the track olt the hind wheel; the llange ot the outside dotted line, the track oi' the tore wheel in `making a turn; the solid line (d), the outside track as dellected in my invention. rlhe space (ce) between the black and dotted lines is to be composed ol concrete.

l'l'aving vl'ully described the above roadway, l. claim as my invention:

l. A roadway composed ol: concrete having parallel tracks which are lirmly held together and kept in place by integral cross bars ol' the same material, thus `forming a solid roadway and doing away with all inecl'ianical appliances tor holding the tracks together. Y

2. A turn in such roadway with outside rail (.lellected toward the inner rail so as to allow the hind wheels ol a motor-propellml vehicle l'ree play and vet remain upon the track in making the turn.

ln testimony that l. claim the 'loregoing as my invention, l allix my siginiture in the presencel ot two witnesses this eleyenth day ol" August, A. l). 1.906.
